FIX: Security Information Is Not Synchronized |
Q165309
The information in this article applies to:
- Microsoft OLE Libraries, used with:
- Microsoft Windows 95
SYMPTOMS
If client "A" initializes COM, then client "B" starts and makes a remote COM call, an attempt by Client "A" to make a secure remote COM call fails with error RPC_E_NO_GOOD_SECURITY_PACKAGES.
CAUSE
The problem occurs because security information is not being synchronized properly if, when it is time to launch Rpcss.exe in a client, COM finds that it has already been launched.
RESOLUTION
You can work around this problem by pre-launching Rpcss.exe before launching the client process. A convenient place to do this is in the registry at HKLM\Software\Microsoft\Windows\CurrentVersion\Run (launches when the shell loads) or \RunServices (launches immediately upon machine boot, that is, before login). Add a named value (any name) and a value of "RPCSS.EXE".
STATUS
Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.
This was corrected for DCOM on Windows 95 in build number 518.
MORE INFORMATION
NOTE: There are other reasons a client application may not be able to communicate with a remote object.

Q165300 BUG: Remote COM Calls Fail Because RPCSS Is Not Started
